Narok, Kenya, Feb 6 (Swara) – A devastating wildlife poisoning incident has claimed the lives of multiple lions and hyenas in Pololeti Game Reserve, Tanzania, near the border with Kenya’s Maasai Mara National Reserve. The poisoning followed a livestock attack on the night of February 1, when a breakaway group from the Sopa/Oloolaimutia lion pride, known as the Border Pride, killed a cow, the Mara Predator Conservation Programme reported on Thursday.

Among the casualties are three adult lionesses, a pride male named Osopia —who was wearing a Mara Predator Conservation Programme tracking collar—one cub, and at least 13 hyenas. A second pride male survived the poisoning and is receiving treatment. Four other adult lionesses and their cubs, who did not feed on the poisoned carcass, have been sighted in good condition.

Authorities from Kenya and Tanzania have launched a joint investigation into the incident. The Kenya Wildlife Service (KWS), Tanzania’s Wildlife Authority, and Narok County Government have taken charge of the case, leading to the arrest and arraignment of five suspects at the Narok Law Courts. The poisoning site has been secured, and contaminated remains have been disposed of under veterinary supervision to prevent further wildlife casualties.

The Mara Predator Conservation Programme was working with various stakeholders to strengthen efforts to mitigate human-wildlife conflict through community engagement and conflict prevention protocols.

Conservation officials have commended the swift response of the Maasai Mara National Reserve Chief Park Warden, KWS, Tanzanian authorities, and all stakeholders involved in addressing the crisis.
